Abstract
A microswitch is provided near each end of each grooved roller. The microswitch has a rod-shaped contact shoe, and is operated if a wire derailed from the grooved roller contacts the contact shoe. An operational signal is sent from the microswitch to a control apparatus, and the control apparatus receives the operational signal so as to detect that the wire is derailed.
